< p> Question 8: What are the safety measures at road construction sites? Before construction, the site must be treated with "three connections and one leveling". When building temporary access roads, the safety of vehicles and pedestrians must be ensured. There are clear signs and traffic control measures. Conduct surveys to understand temporary water and electricity usage at the construction site and draw sketches. Provide water and electricity safety education to all construction workers, and strictly abide by the certification system for special staff.

Before construction, clearly mark the pipelines buried underground and provide detailed explanations to the construction personnel. When excavation passes through dangerous structures such as cracked walls and crooked chimneys, they must be supported and reinforced in advance. Set up protective fences at benchmark points and electric poles, and formulate practical and feasible safety construction plans for road sections prone to landslides during rainy season construction.

Safety signs, dangers, warnings, symbols and slogans prescribed by the state are hung in the construction area to warn people of the scope of protection and dangerous areas.

Question 9: What are construction safety technical measures for construction projects? Construction safety measures are to prevent casualties, machinery and other property losses, etc. In fact, it is easier for us to ignore these, and only then will casualties occur, like in Wuhan The incident was caused by workers' neglect of safety, which caused the elevator to collapse and cause heavy casualties. These are worthy of our reflection. I personally often participate in observation meetings related to safety issues. At the observation meeting, I met the senior management of China Construction Engineering Corporation 3 Engineering Group Co., Ltd., using handheld 3G monitoring to complete a dynamic supervision model, allowing us to control security in real time and reduce This kind of thing happens.

Question 10: What are the safety measures for the construction of large formwork projects? 1.
